Question
I lost my only child in October and her husband has taken up with his friend from work
Answer
First of all, it's not all that uncommon for men to begin dating. Sometimes it's because they're seeking comfort. Other times, it's because they had a really good marriage and are moving on. One of the ironies of grief is that the better the relationship was, the easier the grief.
I can't say which it is for him or whether there's another reason. What I do know is that family members often grieve in different ways and in different time frames. It's one of the reasons, families often have a hard time supporting each other. That and everybody is so absorbed in their own grief that they don't have a lot of emotional energy left to support anyone else.
It certainly makes sense to me that you as her mother and he as her husband would be in very different emotional spaces right now. So though it may be difficult for you to see him dating, I would encourage you to tend to your own grief and let him tend to his.
That may not be what you want to hear, but I hope it helps nonetheless.

I do talk about the difficulties families have while they're grieving a shared loss on pages 84-86.
